Definition
Donchian Channels are a technical trading tool created by Richard Donchian that help traders determine market volatility and identify potential market breakouts. They consist of three lines generated from the highest highs and lowest lows of a security over a specified period, along with a midrange line to assist in measuring the average price over that same period. Trader’s walking on clouds of technical signals — it all looks easy from above until the clouds clear and reality kicks back in!
How it Works:
- Upper Band: The highest price over the specific time frame.
- Lower Band: The lowest price over the specific time frame.
- Middle Band: The average of the upper and lower bands.
Donchian Channels vs Bollinger Bands
| Feature | Donchian Channels | Bollinger Bands |
|---|---|---|
| Calculation Method | High/Low over defined periods | Moving Average ± Standard Deviations |
| Number of Bands | Three (Upper, Lower, Middle) | Three (Upper, Lower, and Mid Bollinger) |
| Main Focus | Breakouts & Trend identification | Price volatility & Mean reversion |
| Application | Simple trend following | Detailed analysis of price fluctuation |
| Flexibility | Works across various asset types | Primarily for stocks and forex |
Example Calculation
Let’s say we want to calculate the Donchian Channel for a stock over a 20-day period:
- Identify the highest high (HH) and lowest low (LL) over the last 20 days.
- Calculate the Upper Band: \( \text{Upper Band} = HH \)
- Calculate the Lower Band: \( \text{Lower Band} = LL \)
- Calculate the Middle Band: \( \text{Middle Band} = \frac{HH + LL}{2} \)
Here’s a handy formula image using the Hugo-compatible Mermaid syntax:
graph TD;
A[Price Data] -->|Period = 20 days| B[Highest High (HH)];
A -->|Period = 20 days| C[Lowest Low (LL)];
B --> D[Upper Band: HH];
C --> E[Lower Band: LL];
D --> F[Middle Band: (HH + LL) / 2];
Related Terms
- Trends: The general direction in which a market or price is moving; can be upward, downward, or sideways (mimicking a confused pigeon).
- Breakouts: When a security moves outside a defined support or resistance level with increased volume (often leading traders to declare “Eureka!”).
- Volatility: A statistical measure of the dispersion of returns for a given security, often associated with larger risk and opportunity (and sometimes spontaneous fireworks).
